چکیده
We tested the efTect oC the addition oC biosolids combined with a native rnycorrhizal inoculum (Arbuscular Mycorrhizal Fungi [AMF]) 00 growth oC a native Australian grass, and 00 trace element stabilization oC sulphidic gold mine tailings. A glasshouse trial was established 00 four substrates: tailings (T); tailings with a layer oC 5 cm topsoil (TS); tailings amended with 100 dry t ha-1 biosolids (LB), and tailings amended with 500 dry t ha-1 biosolids (HB). Pots oC 1.2 L oC capacity were established; sorne were inoculated with a mixture oC Glomus sp. (WUM51-9227), Scutelospora aurigloba (WUM51-53), and Acaulospora levis (WUM46) culture mix, and others were uninoculated controls. Seeds oC the native Australian grass, Bothriochloa maera were sown in the pots. Root inCection, plant biomass production, nutrients and trace element concentrations in shoots were investigated.

The potential of three arbuscular mycorrhizal fungi (AMF) - Glomus mosseae, G. fasciculatum and G. intraradices- to enhance the production of essential oil and plant growth parameter was investigated in sweet basil (Ocimum basilicum). The AMF inoculation significantly increased plant height, fresh and dry matter yield, oil content and oil yield as compared to non-inoculated basil plants. Essent...

Iran is the largest producer of saffron (Crocus sativus) in the world. More than 80% of higher plant species have a mutual relationship with mycorrhizal fungi, which enhances the plant growth and its productivity. With identification of native arbuscular mycorrhizal fungi and their application, it could be possible to expand saffron cultivated area and increase the performance of arable lands. ...

We examined suitability of arbuscular mycorrhizal fungi (AMF) associated with cool-season nonnative forages on reclaimed surface-mined land in southeast Ohio for establishment of native warm-season grasses. The goal of establishing these grasses is to diversify a post-reclamation landscape that is incapable of supporting native forest species. A 16-week glasshouse study compared AMF from a 30-y...

Arbuscular mycorrhizal fungi (AMF), a special microorganism can connect soil and a plant directly, plays an important role in environmental remediation [1]. When the plant is in the heavy metal adversity, mycorrhizal association can enhance the resistance to the metals of plants [2]. Chen et al. [3], reported Cu uptake by four kind of mycorrhizal plants including two native plant species, Coreo...

The aim of this study was to examine the symbiosis relationshipbetween some arbuscular mycorrhizal fungi (AMF) and Salsola laricina (Chenopodiaceae), a non-mycotrophic plant speciesand its effect on improving plant growth parameters. Initially, the development of AMF density was monitored through two parameters including evaluation of mycorrhizal colonization of plant roots and density measurem...
